My Projects

I bought the CodeAlarm CA-145 off eBay for a reasonable price, but since I just installed a better, more expensive alarm system, and since the CA-145 is an "expansion pack", not a system by itself, I figured I could hack around with it a bit :)

This circuit is used to trigger a camera's electronic shutter circuit when a flash of lightning is present. This circuit would also work for photographing fireworks displays or other events involving flashes of light.

It uses a photo-darlington sensor that looks through the viewfinder, and triggers the camera when the light is bright enough.

Description:
In essence, this is Dave Baum's BugBot, (No copyright infringement intended). I added an extra set of antennae (To be able to sense further up, so it wouldn't get stuck under the bottom of a chair, counter, etc). I also made the speed faster in the program so it can run around the room a little more efficiently.

Description:
There is one motor to move the whole arm up and down, and one motor to open and close the hand. Possible upgrades could include pneumatics to raise and lower or open and close the hand, rotating arm, maybe even wrist motion.

Description:
The robot moves forward until it hits something, (The wheel is forced upwards enough to activate the touch sensor behind), then it moves backwards, turns slightly, and moves forwards again. It also has a light sensor on the back for line-following.
